It's sponsored by Minnesota for Marriage — a coalition that supports the definition of marriage as the union of one man and one woman and supported last year's failed effort to put the current ban on gay marriage into the state Constitution.

The group says it wants the current state laws regarding marriage to stay on the books.

Scheduled speakers at the rally include Brian Brown, president of the National Organization for Marriage, and Teresa Collett, a professor of law at the University of St. Thomas.

The group is urging its supporters to meet with their legislators that day, said Crystal Crocker, director of grassroots and messaging for Minnesota for Marriage. She's quoted in the Catholic Spirit newspaper:

“We’re gathering together and energizing ourselves for this effort, but the most important point of the day is to go in and actually meet with your legislators,” she said. “They work for us and they should be meeting with us.”

Jason Adkins, executive director of the Minnesota Catholic Conference, part of the Minnesota for Marriage coalition, said supporters of traditional marriage need to spread the word. He told the paper:

"We’ve got to get the people of Minnesota to say, "Keep marriage the way it is,' " he said. "Our message is: Don’t mess with marriage."
